I. llllllllllll Patented Got. 9, 1934 UNETED STATES PATENT GFFECE VREENFORCED PLASTIC STRUCTURE Alexander Dickson, Brooklyn, N. Y.

Application April 30, 1931, Serial No. 534,077

4 Claims. (Cl. 'l2-71) The invention relates generally to reenforced plastic structures but primarily to walls of dwellings, apartment houses, etc., and to ceilings therefor, the object being to provide an improved re- 4enforced structure which may be easily constructed, will be rigid and durable and will be sound-proof to a high degree.

With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is an elevation partly broken away, looking upwardly against a ceiling constructed in l5 y.accordance with my invention, and the plaster being omitted.

Figs. Zand 3 are verticalr sectional views on lines 2 2 and 3--3 of Fig. 1.

Fig. 4 is a view similar to Fig. 3 but showing a 2Q slightly diiferent construction.

Fig'. 5 is a View similar to Fig. 2 but showing a somewhat modied structure.

Figs. 6 and 7 are detail vertical sectional views showing partition walls constructed in accordance with the invention.

Fig. 8 is a fragmentary perspective view showing other featureswhich may be used in partition wall constructions.

In Figs. 1, 2 and 3, a reenforced plastic ceiling is shown constructed in accordance with the invention, said ceiling being disposed under conventional wooden joists 10. Secured to these joists and extending longitudinally thereof, are flat metal plates 11 whose lower portions project downwardly beyond the joists and are provided with longitudinally spaced upper openings 12 and with longitudinally spaced lower openings 13, said openings being preferably although not necessarily disposed in pairs. Nails 14 are shown for 'securing the bars or plates 11 to the joists 10, and sound-deadening material 15 is preferably interposed between said joists and said plates or bars.

Upper rods 16 extend transversely between the /lplates or bars 1l and are received in the openings 12, and lower rods 17 similarly extend between said plates or bars and are received in the openings 13, and if desired, the parts 11, 16 and 17 be welded together at suitable points, as devvnoted at 18. Wall board 19 such as conventional plaster beard. nbre board or insulating board, eX- tends between the plates or bars 11 and between the upper and lcwer sets of rods 16 and 17, said reds holding the wall board against bowing when v applying plaster to the lower side of said Wall board and thereafter reenforcing the entire structure.

Wedges or other spacing means 20 are preferably .inserted between the wall board 19 and the lower rods 17,v holding the 'wal-l board solidly 60 against the upper rods 16 and so spacing the parts 17 and 19 as to allow the `plaster 21 to readily key around the rods 17. These rods are entirely embedded in the plaster 21, as clearly shown.

After securing the plates or bars 11 in place, inserting the rods 16, placing the wall board 19 and rods 17, and inserting the wedges or the like 20, the plaster 21 is applied, it being preferable to use the usual scratch coat, brown coat, and finish 7() coat successively, and it will be observed that the lower edges of the plates or bars 11 may well act as guides fora screed for smoothing the plaster before application of the nish coat. This linish coat however extends under and covers the lower edges of the plates or bars 11. During application of the plaster, the' rodsl 16 hold the plaster Iboard against appreciable upward bowing from the pressure of `the trowel, and the lower rods 17 obviously prevent any appreciable sagging of said wall board, these rods later becoming entirely embedded in the plaster to reenforce the latter. The entire structure is unusually rigid, durable and sound-proo-f and is especially adapted for small dwellings and apartment houses, though not restricted to any particular field of use.

In Fig. 4, the bars or plates 11a are of channel form instead of being entirely dat, and I have shown them secured to parts 1Ga of a monolithic floor, by means cf expansion bolts 14e. 90 Otherwise, the structure shown in Fig. 4 is identical with that above described, and hence a number of the same reference characters have been used.

In Fig. .5, the construction is identical with that described in connection with Figs. 1 to 4, with the exception that the plate or bar 11b is formed with upper slots 12e and with lower slots 13a for receiving the upper and lower rods 16 and 17.

As other parts shown in this view correspond to parts described in connection with Figs. 1 to 4,

the same reference characters have been applied to them. A

In Fig. 6, partition or other wall studs are formed by the bars 11C, said bars having ver- 101ir tically spaced openings 22 for the purpose of re- -ceiving rods 23 which are disposed at opposite sides of wall board 24. Plaster 25., preferably the usual scratch coat, brown coat and finish coat, is applied to one or 'bo-th sides of the plaster 110 board 24, both sides being of course plastered when forming a partition wall.

Each opening 22 preferably embodies an enlarged central portion 26 through which electrical conductors and the like may be passed, and two tapered end portions 27. The lowerrnost of these end portions insures that the rods 23 shall wedge against opposite sides of the wall board 24, and by having both ends of the opening 22 tapered, either end of a stud or the like l1c may be used upwardly.

In Fig. 7, a construction very similar to that illustrated in Fig. 6, is shown. In this View, the stud or the like 11d is provided with spaced openings 22d corresponding to the openings 22, each opening 22d being provided with a tapered lower end 27d and with a relatively large upper end 26d through which conductors and the like may pass. The reference characters 23, 24 and 25 in this view denote the same parts as in Fig. 6.

In Fig. 8, the bar or stud 11e is provided with spaced rows of relatively small openings 22e to receive the rods 23, and other openings 28 are provided through which to pass conductors, pipes, etc. All of the studs 11C, 11d, and 11e are preferably of channel form as seen in Fig. 8, but could of course be of other :cross-sectional form.

It will be seen from the foregoing that novel and advantageous provision has been made for carrying out the object of the invention, and while the details disclosed may be considered as preferred, numerous variations may be made within the scope of the invention as claimed.

I claim:-

1. A reenforced plastic structure comprising wallboard, openwork means at one side of and co-extensive with said wallboard for holding it against bowing, means for holding said wallboard and said openwork means in assembled relation,

VVinserts between said openwork means and said wallboard holding the latter spaced from the former, and plastic material applied to said side of said wallboard, said openwork means and said inserts being imbedded in said plastic material.

2. A reenforced plastic structure comprising wallboard, spaced rods at one side of and coextensive with said wallboard for holding it against bowing, means for holding said wallboard and said spaced rods in assembled relation, inserts between said wallboard and said rods for holding the former spaced from the latter, and plastic material applied to said side of said wallboard, said spaced rods and inserts being imbedded in said plastic material.

3. A reenforced plastic structure comprising wallboard, spaced bow-preventing means at opposite sides of said wallboard for holding it against bowing, means for holding said bow-preventing means and wallboard in assembled relation, inserts between one side of the wallboard and the bow-preventing means at said one side of said wallboard, said inserts spacing said one side of the wallboard from the bow-preventing means at said one side and holding the other side of the wallboard against the bow-preventing means at said other side, and plastic material applied to said one side of said wallboard, said bow-preventing means at said one side of the wallboard and said inserts being imbedded in said plastic material.

4. A reenforced plastic structure comprising wallboard, spaced rods at opposite sides of said wallboard for holding it against bowing, means for holding said rods and wallboard in assembled relation, inserts between the rods and one side of the wallboard for spacing the former from the latter and holding the other side of the wallboard against the rods at said other side, and plastic material applied to said one side of said wallboard, said rods at said one side of said wallboard and said inserts being imbedded in said plastic material.
